numb-RUNNING Device.

SPECIFICATION forming part of Letters Patent No. 667,849, dated February 12, 1901.

Application tiled November 8. 1899. Serial No. 736,248. (No model.)

To all whom it may cm2/cern:

Be it known that I, ALFRED B. MORSE, a citizen of the United States, residing at Easton, county of Bristol, and State of Massachusetts, have invented an Improvement in Quill-Retaining Devices, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My present invention is an improved device for retaining and centeringpaper or other tubes or quills, such as are used in connection with thread-winding machines. These quills or tubes, as is well known, are frail, being usually made of paper, and are subjected to exceedingly rapid action of the threadguides, which reciprocate longitudinally of the quills in guiding the thread to the quills for winding thereon, and accordingly it becomes necessary to provide supporting means capable of automatically and accurately centering and giving internal support to the` quills, and also in view of the advances in the art ot" winding-machines it becomes necessary for the same reason to provide specialmeans whereby the quills so centered cannot become detached from or disturbed on the quill-spindle during Winding'. To this end I have devised a retaining device which, stated in general terms,"comprises a body, preferably hol low, on which the tube or quill is mounted, said body carrying or containing a movable tube engaging device and being provided with means for actuating said engaging device and causing it to grip and retain the tube in proper position.

Stated more in detail, my in vention'includes radially-projecting locking-pins arranged to be wedged into gripping contact with the inner end of the quill, the preferred form of the quill-holder also having wedge-shaped collars or surfaces to engage the inner surface of the quill as the latter is pushed onto the holder-spindle, thereby centering and supporting the quill in properly-retained position.

The details of construction and further advantages of my invention will be pointed out in the course of the following description, reference being had to the accompanying drawings, illustrative of a preferred embodiment thereof, and the invention Will be more particularly defined in the appended claims.

In the drawings, Figure I is a vertical longitudinal section of my improved quill or bobbin-retaining device, and Fig. 2 is a fragmentary view in section of a portion of a modified form thereof.

For convenience of illustration I have shown an ordinary conical quill or tube q and have shown the sameas mounted upon a usual quill-spindle 7c; but it will be understood that I am in no wise limited in this particular. Especiallyin high'speed thread or yarn Winding machines it is essential that the quill should be quickly and accurately placed in position on the quill-spindle, and for this purpose I have provided a conical engaging surface 7e adjacent the inner `end of the quill or tube holder to receive the larger end of the tube and direct the same quickly and accurately to a similarly beveled or conical surface 7c2at the rear end of the quil1-holder, this surface 7a2 preferably having a shoulder 7c3 to limit the inward movement of the quill. At its forward end I provide the holder with a movable collar or Wedge-shaped portion 7a4, yieldingly held forward by a suitable spring 795, so as to automatically center the quill and hold the same rigidly and rmly in proper supported position, as will be evident viewing Fig. l. At its inner end the holder carries suitable tube-engaging devices, herein shown in the form of radially-operating pilinger-like pins 7c, reciprocating through perforations in the holder and provided within the holder with springs 707, normally holding the pins in inoperative retracted position. The quill-spindle 7c is hollow or centrally bored, as indicated at 768, and provided with an actuator 7c, herein shown in the form of a rod, having a wedge-shaped portion 7910, preferably at its inner extremity, adapted to engage the beveled inner ends 7012 of the tubeengaging devices or pins 766. Bypressing inwardly the rod 705 the plungers 0r pins 7c6 are instantly projected radially, so as to prick into and hold the quill q, placed on the quill spindle or holder.

In Fig. 2 instead of the coiled springs 7c7 (shown in Fig. l) I have provided a leaf-spring 7.513, serving the same purpose and operating in much the same manner as the coiled springs ICO already explained, and in operation the quill is quickly and may be roughly or inaccu rately shoved to the left on the body of the spindle or holder and will instantly be received and automatically adjusted into proper position by the shoulder 7o until its inner end is in proper position on the [lange k2, the larger end of the quill or tube being automatically directed into proper position by the successive conical surfaces or ledges. Inasmuch, however, as quills are not always the same size, but in actual practice are somewhat irregular, I have provided the yielding centering device 7a4, already explained, for engaging the inner surface of the quill slightly back of the forward end thereof, so that as the quill is shoved onto the quill-spindle the conical collar or annular wedge-block 7a4 yields sufficient-ly to permit the quill to be moved the required extent to the left, and yet at th'e same time it presses continuously against the inner surface of the quill, so as to firmly support the same in proper centered position. The actuator 109 is then shoved into the bore las, and upon coming into engagement with the beveled ends ot' the tube-engaging pins 706 instantly forces the same outwardly into gripping and retaining engagement with t-he tube on the body of the holder.

While I have herein shown my invention in its preferred form and with all the parts assembled as I prefer to use them, yet it will be understood that many changes and modifications may be resorted to and many substitutions employed with certain features thereof without departing from the spirit and scope of my invention, and accordingly I wish it understood that I am not otherwise limited than as expressed in the claims.

Having fully described my invention, what I claimas new, and desire to secure by Letters Patent, is-

1. A h'older for paper or other tubes, consisting of a body adapted to be surrounded by the tube, a tube-engaging device carried by and movable in said body, a spring automatically retaining by its spring-pressure said engaging device in its inoperative position, and a rod longitudinally movable against said device for moving it outwardly against the action of said spring, substantially as described.

2. A holder for paper or other tubes, consisting of a body adapted to be surrounded by a tube, and tube-holding means including a plunger-like engaging device capable of being driven radially into the material of the tube, and means for rigidly and unyieldingly driving said engaging device directly into the material of the tube, whereby the tube and engaging device are positively forced into biting or interlocking engagement, substantially f as described.

3." The combination with a spindle having a central bore and a body surrounding said bore and adapted to receive upon it a paper or other tube, of a suitable engaging device sustained in said body, and an actuator adapted to be inserted in the hollow spindle to move the engaging device and cause it to engage and hold a tube, substantially as described.

4. In a holder for paper or other tubes, a body adapted to receive upon it the tube, a radially-movable engaging device having a coperating spring to maintain the engaging device in its inoperative position, and an actuator engaged by hand and moved relatively to said body to act upon the said engaging device and move it to effect the engaging of the tube for retaining the latter in position, substantially as described.

5. `A holder for tubes or quills, comprising a quill-spindle provided at its inner end with outwardly-movable pricks for engaging a quill or tube,wedging means for moving said pricks outwardly, conical or wedge-like projections along said spindle for directing the tube into position, one of said wedge-like parts being yieldingly movable to accommodate it to variious quills, substantially as described.

6. A tube-holder provided at its inner end with means to grip and retain a tube and at its outer end with centering means comprising a collar or wedge, and a spring normally moving said collar into wedging engagement with the tube, substantially as described.

7. A tube-spindle axially provided with a wedge-rod, locking pins or pricks carried by said spindle at the inner end thereof and adapted to be forced outwardly by said wedgerod,said pins being arranged to project against the inner end of the quill and retain the same, substantially as described.

8. In a device for retaining a tube on a quillspindle, the combination with said quill-spindle of a yielding centering device for engaging the inner surface of said tube adjacent the smaller end thereof, and means for engaging and holding the inner or larger end of the tube,^substantially as described.

9. In a device of the kind described, aquillspindle provided along its length with a plurality of sloping or conical projections successively larger toward the inner end of the spindle for directing the tube quickly and automatically into proper position, one of said projections being movable on the spindle and normally held yieldingly forward to properly center the tube and support the same in operation, substantially as described.

In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.

ALFRED B. MORSE.
